In certain parts of England the treated potable water is stored in underground reservoirs prior to being distributed to homes and businesses. These underground tanks are typically constructed of concrete or brick/block with a concrete reinforced roof. The land above these reservoirs is used for purposes such as farming which includes the use of fertilizers and chemicals. Constructed 30 to 40 years ago, the concrete roofs of the reservoirs have become porous potentially allowing dirty rain water and farming chemicals to penetrate the concrete and enter the drinking water. The customer was looking for an effective long term solution of sealing the reservoirs that did not require rebuilding or taking them out of service.
Equipment that is used to move waste operates in a very demanding environment. As garbage breakdowns, chemicals are released and can combine with other materials to create caustic runoff. In addition to eroding metal parts on expensive equipment, this runoff can also damage rubber and even cause unhealthy situations for workers. Replacement is costly and time consuming.A city municipality was experiencing corrosion issues in the tray that contains the hydraulic compacting ram and hoses of their trash compactor.The corrosion was accelerated by the caustic runoff from the waste.The City needed a solution that would resist the runoff, protect the hydraulic equipment and increase the overall maintenance cycle of the equipment. They needed the solution in a time efficient manner preventing downtime of the equipment.
Sewage purifying tanks, like these from the Emek Hefer Region of Israel, are designed to purify waste water from the surrounding town. Waste water contains many harsh substances that slowly ingress into the walls and floor of the tank, degrading the metal and causing the sewage to leak and contaminate the groundwater. A solution was needed to provide a watertight barrier that could prevent the numerous chemicals and acids from seeping into ground water. The chosen application would have to offer a very quick turn-around to allow the water purification system to return to service with minimal disruption.
Impact and abrasion can easily wear away the thin layer of protection paint on service vehicles exposing the metal beneath to corrosion. The resulting of deterioration of the metal will require maintenance or re-placement of the part. It also de-tracts from the overall appearance of the vehicle and image of the company. Additionally, employee steps can become slippery when exposed to the elements increasing slip and fall hazards. A national railway company wanted to protect their service vehicles from corrosion while maintaining the professional corporate look of the company. They also wanted employee walk areas to be protected against slip resistance.
The world’s largest company in the field of sea water desalination (SWCC) consulted LINE-X to find a solution to protect the company’s brine drain channels. Each desalination plant consists of several production units. Each unit has a drain channel that allows the return of brine to the sea water. The brine has a very high salt concentration and is delivered at a high temperature 50-80 C to the sea through concrete channels.Over time the concrete channels suffered great structural damage. Salt water penetrated through the concrete to the structural steel leading to corrosion and failure. The channel walls were critically damaged and falling apart in several areas.
Recycle bins throughout U.S. National Parks take extreme abuse. They are continuously exposed to severe weather, sand storms, and UV damage. The interior of the bins are equally damaged by such items as garbage, aluminum cans, glass bottles, and food waste. These elements degrade the appearance and functionality of the bins. The abuse wears away the thin coat of paint used to protect the metal underneath creating an opportunity for rust and corrosion, while also turning an important asset to the park into an eyesore. Recycle bins usually require replacement in less than a year. The National Park Service needed a solution that would not only protect the recycle bins, but would also keep the bins aesthetically appealing to the public. In addition, they required the solution to be cost effective
Due to urban sprawl more and more communities and engineers are taking additional steps to protect and extend the service life of new and existing wastewater structures. A municipality in one such area controls a pumping station that has been degrading slowly over time. The walls of these stations are particularly susceptible to the corrosive environment and will easily deteriorate without protection. As infiltration and the effect of corrosive gases are the two primary causes of deterioration in a collection system, the addition of a corrosion barrier to a new structure will not only ensure a longer service life to the system, it will make the rough concrete surface easier to clean.
Power Transmission Towers often rust and corrode over time, and without proper maintenance, utilities may need to invest in untimely and costly replacement. Because towers are sometimes located close to major roads, it is important to the surrounding community that these structures are properly maintained. In the past residents have complained of the visual appearance of the towers. As a result, this customer needed a protective coating that is aesthetically pleasing while it also protects the towers from rust and corrosion.
Many law enforcement agencies provide armor shields to protect their officers on duty. The shields are made of almost an inch of dense KEVLAR fiber wrapped in a nylon fabric, and are very expensive to replace. Large shields can run up to $2,000 each. Normal use conditions cause the thin protective nylon fabric to fray and tear easily, exposing the KEVLAR underneath to moisture. Water causes KEVLAR to expand, and the shields deteriorate quickly. With such a high price tag, law enforcement needs a way to extend the service life of its protective equipment.
